Multi-rate OC-12/STM-4 SFP Multimode
Transceivers with Digital Diagnostics
TRXA12MM Multi-Rate
Product Description
The TRXA12MM Multi-rate SFP fiber optic transceivers with integrated
digital diagnostics monitoring functionality provide a quick and reliable
interface for Fast Ethernet, OC-3/STM-1 and OC-12/STM-4 multimode
applications. The diagnostic monitoring functions, alarm and warning
features are provided via an I²C serial interface. The transceivers are
designed to be compatible with the ATM requirements at OC-3/STM-1
(156Mb/s) and OC-12/STM-4 (622Mb/s) data rate, and is suitable for Fast
Ethernet applications.
The TRXA12MM Multi-rate transceivers connect to standard 20-pad
SFP connectors for hot plug capability. This allows the system designer
to make configuration changes or maintenance by simply plugging in
different types of transceivers without removing the power supply from
the host system.
The transmitter design incorporates a highly reliable 1310nm LED and an
integrated driver circuit. The receiver features a transimpedance amplifier
IC for high sensitivity and wide dynamic range.The transmitter and receiver
DATA interfaces are AC-coupled internally. LV-TTL Transmitter Disable
control input and Loss of Signal output interfaces are also provided.
The transceivers operate from a single +3.3V power supply over three
operating case temperature ranges of -5°C to +70°C (“B” option), -5°C to
+85°C (“E” option), or -40°C to +85°C (“A” option). The housing is made of
plastic and metal for EMI enhancement.
